Hi all. I have a Victa stationary motor and would like to ask a few questions about it.

What model is this? the numbers on the motor are 25690 10 and there is a Y stamped above the number. The piston is rounded, does this mean it is a 125cc? . Also the carby looks like it is off a 160cc, a 3S I think. I have had this motor for about 15 years, got it from the local tip for about $10. I did get it to run back then. I have just cleaned it up a bit
and put a new air filter on it. I will try to get it going but I need to bolt it down for that and i live in a unit with no workshop. I intend to take it to a friends place to try it out. Any help appreciated. Trying to work out how to send photos.
